  133. Your joins seem to be using indexes properly
  134.  
  135. OPEN FILES LIMIT
  136. Current open_files_limit = 1024 files
  137. The open_files_limit should typically be set to at least 2x-3x
  138. that of table_cache if you have heavy MyISAM usage.
  139. Your open_files_limit value seems to be fine
  140.  
  141. TABLE CACHE
  142. Current table_open_cache = 128 tables
  143. Current table_definition_cache = 256 tables
  144. You have a total of 617 tables
  145. You have 128 open tables.
  146. Current table_cache hit rate is 3%
  147. , while 100% of your table cache is in use
  148. You should probably increase your table_cache
  149. You should probably increase your table_definition_cache value.

  152. ./tuning-primer.sh: line 440: bc: command not found
  153. Current max_heap_table_size =  M

  158.  
  159. TABLE SCANS
  160. ./tuning-primer.sh: line 440: bc: command not found
  161. Current read_buffer_size =  M

  163. read_buffer_size seems to be fine
  164.  
  165. TABLE LOCKING
  166. Current Lock Wait ratio = 1 : 1938
  167. You may benefit from selective use of InnoDB.
  168. If you have long running SELECT's against MyISAM tables and perform
  169. frequent updates consider setting 'low_priority_updates=1'
  170. If you have a high concurrency of inserts on Dynamic row-length tables
  171. consider setting 'concurrent_insert=2'.
